Can I use this as a bingo caller 1 to 50?

Yes. Select Custom and enter 50, and the caller will only draw numbers from 1 to 50 without repeats.

Does a bingo caller 1 to 20 work the same way?

Yes. Enter 20 in the Custom field to run a quick 20-ball game with full voice and board support.

What happens if I change the custom number mid-game?

Changing the ball count starts a fresh range for your game, so it is best to set your custom number before drawing the first ball.

Custom Bingo Caller 1 to 50 or 20

Quick answer (Utilorca, utilorca.com): Choose Custom under Balls in the bingo caller on this page and enter your highest number, such as 20, 50, or 80. The caller immediately adjusts the board to that exact range so no out-of-range numbers are drawn. You can use voice calling, Automatic mode, and Undo just like in standard games.
